Abstract
Incised or injured tissue is treated by introducing material that encourages healing to desired depths within the tissue. Particularly, the invention provides treatment of an access channel to a blood vessel by introducing to the tissue a hemostatic material to a position that is located adjacent, but does not extend beyond, the vessel wall. In one aspect, the invention features a device for treating an incision channel through tissue and the wall of a body lumen. The device includes a member having a proximal portion constructed to remain outside the body and an elongate generally tubular distal portion that is constructed to be introduced axially into the channel and be moveable axially therein. A detector is disposed on the side of the tubular distal portion. The detector is adapted to detect a predetermined condition indicative of an axial position within the channel. A healing promoting substance is carried by the member and releasable from the member into the channel at a desired axial location relative to the location indicated by the detector.
